Oh I wish I looked that good, such smooth clear skin and such a healthy pallor! Sigh. Not to be.

At any rate, the FrankenLab tutorial in advanced Ill advised luthiery continues. Today’s lesson, removing a faulty neck block.



The neck block in this ES is pawlonia. Not such a bad thing, pawlonia is a traditional cabinet making timber in Asia, and many fine guitars have been made from it. This was not a great piece of pawlonia however. Notice the very rough floor to the neck socket, this is what happens when you try to shape pawlonia with tools that aren’t as sharp as they should be. The fibres resist, tear at the tool edge and pull chunks with them when depart. This leaves you with a moonscape. Not ideal for a critical joint in my view.

By heating up a bridge knife with a micro torch I was able to free the top edges of the block from the guitar sound board. This was made easier by the fact that I only really had to free one side.


Note the complete absence of glue from the top side of the block in the photo (upper side of the joint in the guitar). You can see also from the view of the box with out the block that there is absolutely no glue on the upper side of the joint. The bulk of the glue is on the lower bout side and the face of the block.



You can see the residue of the original factory glue up, in the whiteish residue. I think it is a form of space filling urethane type glue, it is flexible and pliant, even when set. This also makes it a bugger to remove with anything other than a sharp chisel and patience.
The yellow glue residue is the titebond I used when I fitted up the shims to tighten the neck pocket. Potentially my earlier kludging had reinforced the joint, but I guess that is all moot now.

At this stage I want to point out, I am not having a go at PBG, or the quality of the product, I am just laying out what I have found. Not sure that anyone else is likely to pursue a course in advanced stupid like the FrankenLab, and go to these lengths with a kit build, but I do this kind of stupid so other don’t have to, or at least are well informed if they take leave of their good senses and have a crack.

So with the old block removed, some work need to be done on setting a proper curve for the front of the guitar. Some careful reshaping of the neck heel needs to be contemplated and a suitable block of mahogany needs to be fabricated.



Once this has set up for a day or so we will get to measuring plate angles and marking out to shape that block, and setting up to hog and rout the heel pocket.
